CodeNote:

Encoding utf8 = encoding. getencoding (65001); // use code page

Encoding gb2312 = encoding. getencoding ("gb2312"); // use bodyname

Get character encoding byte sequence: byte [] temp = utf8.getbytes ("http://www.my400800.cn
400 telephone reception
");

Encoding method conversion: byte [] temp1 = encoding. Convert (utf8, gb2312, temp );

Obtain the encoded string: String str1 = gb2312.getstring (temp1 );

This completes character encoding conversion.

Encoding. Default is generally in gb2312 format in simplified Chinese OS.
